I'm using jquery to make it easy for AJAX calls.
So I create a class: function cMap(mapID){//vars and stuff}
I go and prototype a function: cMap.prototype.loadMap = function(){ //jquery AJAX call }
Now in the jquery $.ajax({...}); call, I use an anonymous function on the "success:" call: success: function(data){ this.member = data; }
My problem is that inside this anonymous function call I'm trying to call a class member of my cMap class to store the data in from the AJAX call, but it's out of scope. So the JS console in FF/Chrome throws errors about bad value/doesn't exist.
How can I access this class member from inside an anonymous function? Or at least what's a good way to go about doing all this?

How is it possible to define a constant in a virtual class?
E.g. I wrote the following code
tml = {
sayHello : function()
{
alert('hello');
}}
now if I want to add a constant into tml virtual class, what I need to
do?
I tried something like
tml = {
const1 : Integer = 0,
sayHello : function()
or
tml = {
const1 : function(){return 0;},
sayHello : function()
in both case, trying to get - inside tml object - the value of
const1 ... it results in a Object value and not the Integer value I
need.

I have a wordpress website with which I wish to provide content via an iframe on facebook.. Without using a wordpress plugin, I would like to know if I provide a function in jquery that basically says if viewport is equal to 520px then either load this css file or add this body class.. Also, if viewport is = to 520px then hide this element.. I think this can be done but after a lot of searching, I cannot seem to find a definative answer..

<button onClick="return popup('<span onClick='selectShape(1, 1, 1)'>test<span>');" tabindex=Ɖ' onFocus="setFocusColor(0,3)">....</button>
This will work perfectly, but as soon as I need to pass Strings inside the selectShape function, I get stuck.
So the question is, how can I create the following and have it working
......selectShape(2, 'Tricky', ཤx5°').....

I have the following code in one of my pages. My problem is caused, because the method "processEvent" is never called, but I have no idea why. I guess it is broken, because I don't relay the "this" object correctly.
<script type="text/javascript">
var MyClass = function()
{
this.init = function()

I have a document that can contain any number of iframes which have
further copies of the same document (and so on). In practice, we
shouldn't ever have frames within frames, but I'd like to make the
implementation a general case.
Various of the functions in the parent document need to call themselves
in the child documents with the same parameters as they've just been
passed.
Now, I can stick a loop in each function that goes throught the
window.frames array and calls the function for each frame, but for I'd
like to write a function to do this.
It's at this point that my brain explodes. If I limit it to a single
parameter we can do:

I'm in the middle of a JavaScript class, and I've run into a problem with one assignment. ^^; I've been given a pre-written script and HTML code to work with, and am required to modify it. Here's one thing I have to do, via my instructor:
Add an "email" field to this form. This field should also validate as a valid email address. (Hint: after adding the form field to the form itself, your next step will be to expand the function named submitIt() by adding a second if statement to confirm the contents of the email field. You will want to paste into the header and use the validEmail() function which you will find in Script 7.15, highlighted in red on pages 192-3 of your textbook.)
I know how to write the code to validate an email address, but I can't figure out how to call the validEmail() function in the submitIt() function. The code I have now just blanks out all the fields when I hit "submit." Here's the part of the script with the email validation:
window.onload = loadDoc;
function loadDoc() {
resetForm(document.forms[0]);
[code].....

This is a very basic version of what I am trying to do. I have a dynamic list which is set in a table. When clicked, a function is run to set up a new list.. The reason I explain that, is that I need to keep it dynamic.Now for the problem:When I run this page, I have the button made right away, then when clicked it creates the new button. The new button should also run the function to create the new button again, but when I click it, I only receive "error on page".

I'm trying to "progressively enhance" one of my surveys using javascript. Basically, I have rating scales that make use of radio buttons as each point on the scale. Each radio button occupies its own cell in a table. I wrote some functions that will highlight cells on mouseover in a color corresponding to its position on the scale (e.g. the lowest point is red, the midpoint is yellow, the highest point is green). When a radio button is clicked, the background of the button's cell and preceding cells in the same row will be colored accordingly. The functions are working well in FireFox and Chrome (I just have to add a few lines using the addEvent function to make it compatible with IE).
The effect looks a lot nicer when I add a function that makes the visibility of the radio buttons hidden.
However, I want to make sure that there is a fallback option in case the functions that color the cells don't work for whatever reason. I would not want the radio buttons hidden in this case.
Is there a method whereby I can call the "hideRadiobuttons" function only if the other functions are successfully executed?

I am creating a little word guess game, with a random function which picks the word from an array of 10 words. The second function checks if the users' letter choice is part of the secret word. Currently, each time the checkGuess() function is called, the word is changed, probably because I am calling the wordPicker() function from within. The wordPicker randomly chooses the word, then returns that word. All I want to do is pull that word into the checkGuess function, without calling the wordPicker function as it currently does. Here is the code:
Create secret word array
var wordList = new Array("stealth", "telephone", "internet", "nickel", "marine", "instantiate", "method", "function", "television", "monitor")

I'm working through the sitepoint ajax book and had a problem with a particular chunk of code. I eventually tracked down the error and it was being caused because I had:
window.onload = Monitor.init();
instead of:
window.onload = Monitor.init;
Now, one of the sticky threads mentioned that the first is a function call and the second is a function pointer. My questions are:What's the difference between a function call and a function pointer? Why did it cause problems in this particular case? What are the general implications/issues with using one over the other?

Is this correct? The following three lines are equivalent, for
example, [1] can be replaced with [2] or [3] anywhere in a script
without changing the return value and without changing any side effect.
[1] var r = o.f(a,b);
[2] var r = o.f.call(o,a,b);
[3] var r = o.f.apply(o,[a,b]);
( o is an object and o.f is a function. )
The following three lines are equivalent:
[1'] var r = g(a,b);
[2'] var r = g.call(this,a,b);
[3'] var r = g.apply(this,[a,b]);
( g is a function, for example,
var g = function(a,b){return [this,a,b];}. )
